What must you wait for before passing a school bus?

You must wait for the red warning lights to deactivate before passing a school bus because these lights indicate that children are either boarding or disembarking from the bus. This is a critical safety measure designed to protect children who are potentially crossing the road and may be in close proximity to the bus. The red lights serve as a warning to drivers to stop and remain halted until it is safe to proceed. Passing a school bus while the red lights are active is illegal in many jurisdictions and poses serious risks to the safety of children. Therefore, understanding this rule is essential for all drivers, especially those operating emergency vehicles in school zones where children are present.
